Baird needs to make promise on GST: Opp'n

NSW Premier Mike Baird must make it clear there will be no increase in the GST in response to savage federal budget cuts, state Opposition Leader John Robertson says.

Mr Robertson says he is concerned state and territory leaders will forge a "backroom deal" at Sunday's meeting in Sydney to discuss the federal government's plan to cut $80 billion in education and hospital funding over 10 years.

He fears leaders could agree to delay a debate on increasing the GST until after the NSW election next year.

"I'm very worried that there will be some backroom deal done today to delay this debate," Mr Robertson told reporters.

The new premier came out tough after the budget was handed down, saying it was a "kick in the guts" to the state.

But by the end of the week "we saw him almost roll over and have his belly scratched by Tony Abbott", Mr Robertson said.

"Mike Baird will have failed as NSW premier if he comes out of today's meeting with anything less than a plan to fight for every dollar of the $25.5 billion that is being taken out of our schools and our hospitals and a clear statement that there will be no support for an increase in the GST," he said.
